Title: Connector attachment/detachment type semiconductor laser module
Inventor: ISHIKAWA SHIGETA
IPC: G02B6/42
Filed: 1991-01-17
Abstract: PURPOSE:To reduce a production cost by holding the ends of a lens and an optical fiber in a positional relationship in which they are brought into contact with one another in a physical contact state. CONSTITUTION:A light emitted from an LD pellet 1 in an LD package 7 is focused by the spherical surface of a lens 2, and coupled to an optical fiber 3 of an optical connector. The connector is formed of a receptacle 5 and a ferrule 4 for holding the fiber 3. The fiber 3 held by the ferrule 4 is engaged with the receptacle 5. The lens 2 is formed at one end face in a spherical surface and at the other end face in plane by optical polishing or die forming of glass, and fixed in the engaging hole of the receptacle 5 with low melting point glass. In this case, it is so disposed that the plane side of the glass is brought into physical contact with the end face of the fiber 3 of the connector. Accordingly, reflection of the light emitted from the LD at the end face of the fiber 3 is suppressed to a small value.

Title: Door control device for elevator
Inventor: TAKAHASHI MADOKA
IPC: B66B13/14
Filed: 1994-01-18
Abstract: PURPOSE:To provide a door control device for an elevator which is constituted to prevent a door from making collision with passengers when an elevator door is closed. CONSTITUTION:During opening of a door, a cam switch DMS is opened. Since, when relay contacts DCa1 and DCa2 for closing a door are closed, an electric motor DM for a door power is operated through a resistor R, the door is closed at a low speed during the starting of closing of the door. When the door is closed to some position, the cam switch DMS is closed and the resistor R is shortcircuited, whereby a door closing speed is switched to a high speed.

Title: Power unit for ac arc welding machine
Inventor: KANO KUNIO
IPC: B23K9/073
Filed: 1987-01-09
Abstract: PURPOSE:To sustain an arc without driving a high frequency generater at all times by setting the respective coil direction so that the induced voltage generated on the respective 1st and 2nd smoothing reactors becomes in the reverse direction each other while referencing to the load. CONSTITUTION:At the polarity reversing time when the welding polarity becomes a reverse polarity from straight polarity with a transistor 36 being turned OFF from ON the induced voltage V1 in the arrow mark L direction is caused on a smoothing reactor 6a. At this time a magnetic flux is generated on a core and the induced voltage V2 in the arrow mark M direction is generated on the reactor 6b. The voltage V1 is charged to a smoothing capacitor 40. The induced voltages V1, V2 are in reverse direction each other and the negative rectified output voltage rectified by diodes 33, 34 is increased by the induced voltage V2 and impressed on a welding electrode 8 and base metal 9 by adding to the charging voltage of the smoothing capacitor 41 charging the voltages generated on the smoothing reactor 6b at the previous polarity reversing time. The thermoelectron release of the base metal 9 in a revers polarity is thus facilitated to sustain the arc at the transfer time from the straight polarity to reverse polarity head.

Title: Printing device
Inventor: IDE YOSHIHIKO
IPC: B41J35/20
Filed: 1991-01-21
Abstract: PURPOSE:To provide a printing device capable of eliminating the residual amount of a correction tape without increasing the consumption of the ribbon. CONSTITUTION:After the first round of printing, a stepping motor 4 is inched to rotate a ribbon and at the same time, is finely rotated to move a carriage 11 1/60 to the left and then the second round of correction printing is performed. After that, the stepping motor 4 for ribbon holder rotation is moved downward and at the same time, the carriage 11 is moved 2/60 to the right to perform the third round of correction printing. In this case, a reel holder feed member 7 slightly moves backward so that a reel holder 6 no longer receives pressure from the reel feed mechanism. Subsequently, a correction tape 2 is fed backward by the back tension of the reel holder 10. In turn, a printing hammer 12 hits the correction ribbon 2 but the position where the printing hammer 12 hits the ribbon 2 is at the upper right from a position 45 where the first round of correction printing is performed. Thus this hammering action peels off the residual amount of an unused correction tape sticking to the right.
